Wow, that's really impressive - I never really had any issue with how GTA4 looked (I've not gone back recently) but seeing those comparison shots, you can see how ropey some of the stuff was / is.

I know we've had reassurance that the footage / screens we've seen are all current gen, but shit. Those are like night and day. I guess budget and time can make all the difference. If this is what R* are capable of on the PS360, then the next gen version of GTA5 (There has to be one right? especially when you consider the recent PC version rumors) or GTA6 is going to look incredible.
